摘要/Abstract

摘要：对以桐籽壳为原料、用氯化锌法制备活性炭的工艺进行了研究，采用正交试验优化了工艺参数.最佳工艺参数为：料液比质量比1∶2.0、氯化锌质量分数为50%、活化时间60 min、活化温度为60 ℃.在此工艺条件下所制备的活性炭，其碘吸附值为986.35 mg/g，亚甲基蓝吸附值为178.23 mg/g，表观密度为0.423 6 g/mL.

关键词： 桐籽壳, 活性炭, 氯化锌质量分数

Abstract: The process of activated carbon preparation from tung shell was discussed in the presence of ZnCl₂.Based on the orthogonal test,the optimal condition was obtained as follows:the ratio of tung shell to solution (w/w) is 1∶20;the mass fraction of ZnCl₂ solution is 50%;the tung shell is treated for 60 min at 60 ℃.The obtained activated carbon has iodine absorption value of 986.35 mg/g,methyl blue absorption value of 178.23 mg/g and apparent density of 0.423 6 g/mL.

Key words:

tung shell, activated carbon, mass fraction of ZnCl₂
